Unrecognized function or variable 'dropTrailingDims' in dlarray - in text extraction code.

Hi Techies,

Currently, I am working on the text extraction project. For that, I am using CRAFT + OCR example code from mathworks library. When I test the code, it was working fine and I am doing some update in the preprocessing module prior to this module. After integration of module, it was working fine but suddenly, throwing some error and warning. Below I have provided the error and warnings for your reference. Kindly check and assist me on this.

Getting the same error with matlab live script as well. Below I have provided the snapshot for the refrerence. Kindly check and assist me on this asap......

bboxes = detectTextCRAFT(I);
